Cable helix angle measuring device and method

The invention discloses a cable helix angle measuring device and method, the device comprises a soft belt, the soft belt is provided with an angle vertex, a measuring axis and an angle scale line, the angle vertex is located at one end of the measuring axis, and the angle scale line is located at the other end of the measuring axis. The angle scale marks are arranged on one face of the soft belt from large scale values to small scale values of the measuring axis to far positions in the direction perpendicular to the measuring axis, and extension lines of the scale marks intersect at the angle vertex. The flexible measuring device is used for measuring the helix angle and can be attached to the outer circle contour of the cable, and an accurate helix angle measuring value is obtained. In addition, for left-handed and right-handed spiral winding, accurate measurement can be carried out. 本发明公开一种线缆螺旋升角测量装置及测量方法，装置包括软带，在所述软带上设置有角顶点、测量轴线和角度刻度线，所述角顶点位于测量轴线的一端，所述角度刻度线在测量轴线的另一端，且各个角度刻度线沿垂直于所述测量轴线的方向，在软带的一面从所述测量轴线刻度值由大
